Reps in reserve, measured off the bar.

Point your phone at the rack. RIRVana times every rep, reads the slowdown, and writes your next set from what actually happened, not from what you guessed on the way to the water fountain.

Side-on capture of a back squat descent, bar path and knee tracked mid-rep.

Why
Concentric velocity dropped 22% — clear fatigue, a couple of reps left. Prescribed 2 RIR; the reading landed on it, so the load holds.
01

Measured

The camera times the concentric of every rep. Solid, full-contrast numbers are things it saw.

02

Estimated

Velocity loss maps to a reps-in-reserve range with a stated confidence. Purple numbers are things it inferred.

03

Decided

When the reading says there was room, the next set gets more. When it says you were over, the load holds. One line of why, every time.

A block, autoregulated

Load follows the reading.

Nine weeks of back squat in the demonstration block. The jump is taken only when the measured effort said there was room; week four of each wave backs off on purpose.

Who this is for

Lifters who already train close to failure.

The reading earns its keep in the last three reps. If your sets end at RPE 6, a logger is fine. If they end at a grind and you still write RPE 8 in the notes, this is the instrument you were missing.
